The 840 series of pressure transmitters is specially designed for measuring pressure in explosive atmospheres (safety class, EEx ia IIC T4, Ta=-20°C to +80°C) as part of a larger overall system. It contains an integrated signal amplifier. The 840 series of pressure transmitters can be used in media temperatures up to 85°C. If the pressure transmitter is used in other applications, the safety and accident prevention regulations specific to that application must be followed.

When using the PT as a safety component in accordance with the EC Machine Directive,When using the PT as a safety component in accordance with the EC Machine Directive,

When using the PT as a safety component in accordance with the EC Machine Directive, Annex IIc, the equipment manufacturer must take any necessary precautions to ensure thatAnnex IIc, the equipment manufacturer must take any necessary precautions to ensure that

The operator or owner of the larger overall system is responsible for following the safety and accident prevention regulations that apply to the specific application.

When planning machinery and using the PT, follow the safety and accident prevention regulations that apply to your application, e.g.:

• EN 60204, Electrical equipment in machines.

• EN 292, Machine safety, general design guidelines.

• DIN 57 100 Part 410, Protection against electric shock.

• EN 50 014:1997, General Requirements

• EN 50 020:1994, Intrinsically safe apparatus

• EN50284:1999, Special requirements fro Group II Category 1G

** Each flush diaphragm transducer or transmitter is shipped with a DYNASEAL, Dynisco P/N 633014, for the pressure port seal. Recommended torque, for an adequate seal, is 100 in-lbs. Care should be exercised with the low pressure ranges. The flush diaphragm can be inadvertently overloaded with thumb pressure, which can be the equivalent of several hundred psi.

ONSTRUCTION

The PTs of series 840’s are industry standard.

The main advantages are:

• Intrinsically safe EEx ia IIC T4

• thermal stability

• resistance to aggressive media

• insensitivity to electromagnetic radiation (EMC)

UNCTIONSUNCTIONS

UNCTIONS

Through a closed, direct contact measurement system, the PT furnishes an electrical signal that is proportional to the pressure of the media.

The pressure is applied by the medium on the measuring diaphragm. The deflection of the measuring diaphragm changes the resistance of the strain gauge bonded to the measuring diaphragm. The strain gauge is a Wheatstone bridge.

Depending on the model, the integrated amplifier generates an electrical signal (mA) proportional to the pressure.

ESD sensitive component. Electrostatic discharge may damage the PT. Take ESD precautions.

Before mounting the PT, check the process connection carefully.

Before mounting the PT, ensure that the process connection is free from media.

To prevent the PT from sticking permanently in the process connection, coat the thread section of the transmitter with high temperature resistant grease or a suitable parting agent.

Always use a torque wrench when screwing the PT in and out. Do not apply the tool to the housing or housing / electrical connection!

• Screw the PT into the process connection and tighten.

• Earth the machine section with the screw-in trunnion / process connection for the PT in accordance with regulations. The PT must be connected to earth via the screw-in trunnion / process connection.

• Connect the shield of the connecting cable on both sides, making sure it conducts with full and continuous contact.

• When introducing the connecting cable into an EMC compliant switch cabinet, for example, connect the shield correctely (cable gland, conducting, full contact, continuous) to the conductive housing or route it via built-in cable connector that is also connected to the conductive housing.

• Connect unused cable cores or free cable ends correctely to the cable shield on both sides.

ESD sensitive component. Electrostatic discharge may damage the PT. Take ESD precautions.

Always remove the PT before cleaning the machine with abrasives or steel wire brushes or suchlike.

Removing the transmitter if the medium is in solidified condition can damage the diaphragm of the PT.

Do not clean the screw-in section of the PT with hard objects. This will damage the PT!

Always use a torque wrench applied to the designated hexagon collar when screwing the PT in and out. Do not apply the tool to the housing or housing/electrical connection!

• Remove the PT.

• Carefully clean the PT/process connection of the transmitter with a soft cloth, while the medium is still malleable.
